Comments
Boot sequence.
psi is the current unit of pressure measurement.
Step into the hidden calibration mode.
Start of calibration process. The advance-solenoid will be powered up to access the pressure transducer
through valve-port A.
Calibrate the zero-offset, point “A”.
Confi rm the pressure data should be stored to memory.
Calibrating gain is done with two points, starting with point “B”.
First obtain the pressure value on the master gauge (ie 5000 psi). Then use the arrow buttons to match the
LCD value to the master gauge.
Confi rm the pressure data should be stored to memory.
Calibrating gain is done with two points, fi nishing with point “C”.
First obtain the pressure value on the master gauge (ie 8000 psi). Then use the arrow buttons to match the
LCD value to the master gauge.
Confi rm the pressure data should be stored to memory.
Re-confi rm calibration data. Leave “off” to proceed with new calibration data. Only set to “on” to change
calibration data back to factory default settings. Press Arrow button to change.
Save calibration data to permanent memory.
Calibration complete, motor stops and electric valve releases pressure.
